Tata Metaliks

Tata Metaliks (TML), promoted by Tata Steel, has been engaged in the
production of pig iron since 1994. Pig iron is used in the manufacture
of rolling mill rolls, automobile engine blocks, motor and generator
housings, gears, railways and machine tools.

In October 2007, TML signed a joint venture agreement with Japanese
companies Kubota Corporation and Metal One Corporation to set up Tata
Metaliks Kubota Pipes, to manufacture ductile iron pipes. The company,
headquartered in Kolkata, has a capacity to make 110,000tpa (tonnes per
annum) of ductile iron pipes at its facility within the TML pig iron
plant in Kharagpur, West Bengal. TML's other manufacturing facility is
at Redi in Maharashtra.

TML has acquired captive iron ore, manganese, limestone and dolomite
mines towards achieving raw material security. TML has been granted a
prospecting licence for iron ore mines at Dongarpal in Maharashtra. The
company is also pursuing a sinter plant at Kharagpur, 120,000tpa
capacity non-recovery type coke ovens at Redi and Kharagpur and a coal
dust injection plant at Kharagpur. Other projects are captive power
plants at Kharagpur and Redi that will utilise flue gases from the coke
ovens.

The company recently signed a memorandum of understanding with the
Karnataka government for an integrated steel project of 3mtpa at Haveri.
It has received approval for land, power and water supply for the
project, which will be implemented in association with Tata Steel and is
pursuing the allotment of iron mines.

The company produced 506,301million tonnes (MT) of hot metal in FY09-10
compared to 386,685MT in the previous year. In the quarter to June 2010
it reported a profit of Rs10.30 crore against a loss of Rs14.93 crore in
the previous corresponding quarter. Net sales surged 48.12%, to Rs273.21
crore from Rs184.45 crore. Average sales growth in the past three
quarters has been a high 54%. The drawback for TML is that margins are
low (10%), so a slight dip in sales could result in profits falling, as
was the case in 2009. Buy the stock now (current market price Rs138.95)
for a rally at least up to Rs210.

Optimization Of Grinding Machine Grinding To Extend The Life Of The Way

Optimization Of Grinding Machine Grinding To Extend The Life Of The Way

Grinding is used for pulp and paper industry in the fiber cut, the
refiner separating the "heart" consumable parts. Grinding of the use of
life on the refining process yields, energy consumption, safe operation
and grinding machines play a decisive role in various economic
indicators. How appropriate for the specific production grinding to
achieve optimal results, this area has been the focus of research and
development. Refining the process of how to extend the life of the
process grinding methods and measures to be discussed.

1. Grinding wear on the production of

Pulp slurry occurs during poor quality and productivity decline, perhaps
because of grinding wear and tear reasons. Select the best time is to
replace the production of important technical issues.

In Yunnan Province Paper mill 75t / d of mechanical pulp production line
system of Eucalyptus APMP pulp with a second disc mill (KavernerHymac
production) of grinding damage, made into a pulp beating degree is only
20 ° SR, pressure screen good pulp fiber

bundle content of 2%, papermaking of LWC base paper surface strength is
slightly lower.

Mudanjiang Hengfeng Paper Group Co., Ltd. Shanghai paper making
machinery plant the original 2362 machine in operation in 1992, can only
produce about mid-range permeability 30coresta Cigarette Paper .
Purchased the plant poplar, oak, birch, wood and other forging and
grinding of various types, beating equipment easy to wear, and tooth
grinding and material instability, into a pulp production of high
quality cigarette paper can not.

Tracing paper of the "white point" is a small fiber, resin blocks or a
combination, and sometimes the whole site there, especially conspicuous.
Freeman Specialty Paper Inc. found that: site takes too long to use mill
grinding, the feed volume increased, knife spacing, weakened the role of
sub-wire broom, cut off the greater role of the small fibers increased,
should be changed regularly grinding.

Qiqihar Paper Co., Ltd. introduced ANDR IT Z's 200t / d total production
of low aspen APMP line quantitative offset newsprint practice shows that
such place of poplar birch, poplar fiber morphology as the control
process is more important beating; the grinding life of about 2500h;
grinding using the time The longer the lower the beating, tooth surface
passivation on the weakening pulp cut off, thus resulting in reduced
pulp beating degree; role in the process when grinding high
acceleration, grinding teeth wear serious, not to mention beating up and
the degree of plasma material can smoothly through the grinding,
resulting in feed screw plug.

Qiqihar Paper Co., Ltd. single-turn pressure plate mill MRSD58/62
(AndritzSprautBauer Company production) and grinding with two grinding
zone: a broken ring for the area, the grinding of the broken loop region
from 6 tooth slices, material 174PH, dental dam thick, larger distance
between teeth; one for fine grinding ring area formed by the 18-tooth
chip, made of alloy 440, the tooth dam moderate, middle distance is
small; wheel grinding and setting disc grinding gap between the 0.9 ~
1.1mm. Among them, into a grinding mill of the concentration of control
in 28% and 35% Best; into Erduan disc refiner's beating degree of about
17 ° SR, the concentration of control in 22% to 25% of the best; with
the use of time extension into the slurry in order to ensure the
quality, plate mill beating the concentration must be reduced. Broken
areas or teeth grinding teeth are damaged and ditch blocking, grinding
wear serious, if the 30% decline in refining capacity, must be replaced
grinding.

2. To improve the service life of grinding technology methods and measures

2.1 improve the refiner's production level of precision and control

Heilongjiang Star Paper Co., Ltd. 450 double-disc grinding, due to years
of long, quiet drive chassis built office and mobile seat installed
fixed disk Department corrosion, wear a difference of 3 ~ 4mm, 410
direct export to Taiwan office wear bigger 420 around the screw fixed
grinding wear and corrosion resistance and the emergence of larger-type
speakers, resulting in grinding can not be a good fit with the body.
Will move within the plane seat and chassis corrosion surface car to
about 3 ~ 4mm, then cars straight exit station; screw holes drilled to
the depth of processing, into M14, plus pad, and pad with bolt seal
fastening, use the same effect was replaced with new parts, spare parts
save money.

Grinding of the structure, tooth type, tooth surface slope and angle,
and the safe operation of equipment and as a direct impact on pulp
quality. Slurry with a fine-tooth lower beating strength; a fine-tooth
into the pulp fiber to increase the uniformity of treatment to maintain
the fiber length to fiber cell wall faster hydration to promote better
integration of fiber. Beating the high increase in the intensity of the
fiber cut, easy to produce more small fibers; in the same tensile index,
the fine-tooth into the pulp has a high opacity, bulk and air
permeability; on broad-leaved Wood pulp Fine-tooth grinding can save
energy beating, but also reflects its high permeability and opacity, but
also take into account the strength of the fiber. Fine tooth grinding at
the mill for wood pulp fiber and non-wood fiber pulping; fine tooth
grinding casting method is not used, but with a special welding method;
life of ordinary cast iron 3 to 4 times. Grinding designed to a certain
pitch, to avoid a sudden increase in mechanical energy and the local
wear of tooth surfaces. Gradient selection is too small, the resistance
increases feeding, increased load caused by feeding; if a larger
gradient will cause uneven wear, impact grinding life.

Town in Jiangsu Province and Jilin Paper Co., Ltd. Jiang Dadong
integrity Industrial Development Co., Ltd. spun plasma low-intensity
beating of a fine-tooth grinding, more than a year after an application
of that low-intensity beating knife to use the improved bar, width
2.47mm, knife groove width 2.47mm, knife Goushen 6mm. The grinding
material is still used Nitinol alloy, cultural paper in a papermaking
pulp staple line of low intensity, not to adjust operating conditions,
very few fibers cut, silk broomed better; tons of pulp on average from
the 173 ~ 168kWh energy consumption down to 158 ~ 146kWh; Paper Breaking
length to upgrade from the 5632m to 6546m, folding to 48 times from 26
times.

Italian poplar production line used AndritzSprortBauer APMP's plate mill
grinding broken area high concentration gradient is about 1:11 more
appropriate, feed load more stable; coarse grinding zone when the power
gradient 1:250 stability, feeding spiral smooth operation, high into the
pulp beating, wet weight in a better level of grinding longer life
expectancy, the vertical rack to maintain uniform wear, energy
distribution of balance; grinding zone gradient generally 1:800 appropriate.

Scope Of Gold Mining Equipments

The growth of any mine depends mainly on the types of equipments used in
it. They may be high graded or low graded equipments. This varies from
high, small and medium sized companies. Gold mining equipments also
belong to the same category. Gold is the metal being loved by all and
has become a major area of investment. Keeping in mind about the facts
of today's world, the instability faced in the stock markets which is
giving lots of pain to the investors in the stock market, we should
think twice before investing.

The accounts of the industries investing in gold, gold mining and their
equipments are showing very high gains. There has been no fall in the
recent times. In other words, it is the safest way to invest money as
there is surety of returns at a faster pace than any other way. This
investment shines like the beautiful metal gold.

These advantages have given way for a small setback for the companies. A
little of bad also comes hand in hand with the good. The confirmed rates
of growth and increasing demand for gold has urged the miners to go on
strike against the companies asking for increase in their wages. Many
world famous mines and companies related to gold mining equipments faced
this problem for quite some time but however it did not affect the
output of the gold mining industries. The wages of the miners grow along
with rates of gold.

Nevertheless this problem had no specific effect in the growth of the
gold mining companies. The graph of the profit remains to be growing at
a steady rate. The disputes amidst the companies and the miners seemed
not to affect the functioning of these industries. Guarantee in
outstanding profit is the picture of all the people investing in gold
mining equipments. This seems to be the best part of the companies in
this field.

The gold mining factories are also giving good service to the machines
since servicing of the machines plays a very important role for
continuous functioning of the mines. Again by rendering services, the
industries are happy in getting double profits. Many companies around
the world are proving their victory and surely will continue to make an
outstanding yield in money. Gold mining equipment companies are one of
the smartest ways to make money.

Coal Mining Equipment Introduce

Coal mill also called coal pulverzier or coal powder mill is grinding
mill that is used in coal mining industry, such as vertical coal mill.
And in general, vertical mill includes mineral series and coal series.
The first series grinder can be widely used in cement making, power,
metallurgy, chemical, ore industries. And the vertical coal mill also
called coal grinder is the most used machine for coal grinding according
to our mining experience. In some cases, coal mill is not just one
grinder mill, it will include some optional equipment such as vibrating
feeder, vibrating screen, belt conveyors and so on to finish the coal
milling process. So, coal mill is also used widely in many industries
besides coal mining.
Coal mill classification

Coal mill is an efficient tool for grinding coals into fine powder in
coal mining industry. According to its fineness and working principles,
we divide coal mill into coarse power coal mill and fine coal mill.
Coarse powder mill is a kind of new high-tech milling machine to meet
the requirements of coarse powder processing customers. It is the ideal
equipment to replace Raymond mill, ball mill, and other traditional mill
which only process fine coal powder materials.
Coal mill working principle

Raw coal is fed through a central coal inlet at the top of the
pulverizer and falls by gravity to the rotating grinding table, mixing
with classifier rejects returned for re-grinding. Centrifugal action
forces the coal outward to the grinding ring where it is pulverized
between the ring and three grinding rollers. Grinding load, transmitted
from the tension rods through the loading frame to the roller
assemblies, holds the rollers in contact with the grinding ring. The
rollers adjust vertically as the depth of the coal load increases or
decreases.

A nozzle ring on the outside perimeter of the grinding ring feeds
primary air to the pulverizer. Pyrites and tramp metal fall through the
nozzle ring openings to be scraped into a rejects hopper.

A stream of low-velocity air carries the particles of pulverized coal
upward where they enter the classifier inlet vanes. Fine particles
travel to the burners in the primary air stream, but the larger, heavier
particles are returned to the grinding zone for further pulverization.
